[PATCH] D102918: [RISCV] Avoid undef result due to promotion of FPOWI exponent

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I don't think this is the right approach... in particular, messing with target-specific code means that every target that doesn't have 32-bit registers would need to explicitly handle this.

What we should be doing is changing DAGTypeLegalizer::PromoteIntOp_FPOWI so it doesn't generate an FPOWI with a 64-bit operand, so we don't have an issue in the first place.  We can generate the powi libcall from there, I think.
